Problems solved by technology

[0002]CN200880023715.1, this invention discloses a coating method for forming a laminated coating film on a base material, which is applied on the base material through a wet-on-wet process The process of laminating the paint for the lower layer and the paint for the uppermost layer to form a laminated coating film, and performing heat treatment on the laminated coating film, the disadvantage of this method is that the curing speed of ordinary heat treatment is slow, and usually As long as dozens of hours; on the other hand, since the residual solvent in the coating is not completely volatilized when the outer coating film is cured, bubbles are likely to be generated as the climate changes.

Abstract

The invention belongs to the technical field of coating, and particularly relates to a terrace surface coating method and a coating body obtained with the terrace surface coating method. The coating method includes the following steps: (1) primer is coated on the smooth terrace surface, and microwaves are used for heating solidification; (2) paint is coated on the coating surface obtained in the step (1), and ultraviolet light is used for polymerization; (3) finishing coatings are coated on the coating surface obtained in the step (2), and the ultraviolet light is used for polymerization. The coating body obtained with the method has the advantages of being high in curing speed and free of bubbles.

Description

technical field [0001] The invention belongs to the technical field of coating, in particular to a method for coating the floor surface and the resulting coated body. Background technique [0002] CN200880023715.1, this invention discloses a coating method for forming a laminated coating film on a base material. The coating for the lower layer and the coating for the uppermost layer are laminated on the base material through a wet-on-wet process, thereby The process of forming a laminated coating film, and performing heat treatment on the laminated coating film, the disadvantage of this method is: common heat treatment, the curing speed is slow, usually as long as tens of hours; on the other hand, due to the external coating When the film is cured, the residual solvent in the coating is not completely volatilized, and it is easy to generate air bubbles as the climate changes. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the in...
